Description

Technical Field

[0001] The utility model relates to the technical field of rice production, in particular to a dust treatment device for rice production. Background Art

[0002] A large amount of dust and impurities are generated during the rice production process. These dust and impurities will affect the quality and taste of the rice, and even have an impact on the production environment and the health of workers. Therefore, during the rice production process, measures need to be taken to remove the dust and impurities to ensure the quality of the rice and the safety of the production environment. The dust removal device is a device specially used to treat industrial dust and waste gas. It separates dust and impurities from the gas by physical, chemical or electrical methods, thereby achieving the purpose of purifying the gas.

[0003] After searching, announcement number CN220760374U discloses a dust removal device for rice production. In this scheme, by starting the suction pump, the suction pipe at the suction end can collect the dust inside the main box, and then collect the particles shaken off by the vibrating net through the receiving groove. It can effectively collect the dust and particles after screening, thereby reducing the pollution caused by dust to the environment.

[0004] However, since this type of dust collection device mainly uses filters to block and recover dust, some fine dust will still spread through the filters into the rice production plant, resulting in incomplete dust treatment. As the dust adheres to the surface of the filter, it will also cause poor dust treatment.

[0005] To this end, a dust treatment device for rice production is proposed, which has the advantages of sufficient dust removal and anti-clogging, thereby solving the problems in the above-mentioned background technology. Utility Model Content
